Just as he was about to ask the question, Zhang Yang saw Li Yue pull the corner of his clothes and received her eyes.

Zhang Yang followed her to the house, and Li Yue whispered: "Li Chunfeng's math skills are very powerful, and your math skills are also very powerful. ”

Looking at her curiously, Zhang Yang frowned and thought.

Li Yue said with a smile: "I know that your math skills are very good, but Li Chunfeng Dao Chang is a master of math today, and the topic can't be too difficult to avoid people's face, and it's not good for you." ”

Zhang Yang nodded clearly, in fact, there are many famous mathematical problems in this world, pi is an endless number, if you want Li Chunfeng to calculate pi, he will not be crazy.

In line with the heart of not wanting to cause trouble, and not wanting to be disturbed too much in life, the little daughter-in-law still puts herself in her shoes.

Touching her head, Zhang Yang was puzzled: "Do you have to coil up your hair?" ”

Li Yue smiled, "I'm already an adult, aren't all women like this?" ”

Zhang Yang took off her hairpin, and her long soft hair fell down her shoulder, "I still like this look, it's not good for hair to be coiled for a long time." ”

Li Yue grinned, "You can do whatever you want." ”

"So dependent on me?"

"You're my husband!"

Li Chunfeng and the others outside the door didn't know what the horse and Her Royal Highness the princess were discussing, and after studying the half-life arithmetic, it was naturally no problem to deal with a half-sized child, and it also let him see the breadth and profundity of the arithmetic.

In the room, Li Yue whispered: "You can come up with a slightly easier question, whether you can calculate it depends on Li Chunfeng himself." ”

Zhang Yang nodded, "Okay, for your sake." “

Li Yue smiled softly.

In fact, my daughter-in-law's hair is very good and supple, and it would be bad if there was any damage to such a good hair.

In the past, Li Yue's health was not good, and her hair was a little yellow, but now her black hair is very beautiful.

The two walked out of the house again.

Li Chunfeng looked at the couple and said, "Have you thought of the topic?" ”

In the courtyard, the two stood opposite each other, Li Chunfeng did not dare to underestimate the young man in front of him, who could teach Her Royal Highness the Princess, and also let Her Royal Highness the Princess solve the problem so quickly, this person was not simple.

Zhang Yang drew an eight-by-eight chessboard on the ground, a total of 64 grids, "Once upon a time, there was a king who liked to play very much, and he wanted to reward a meritorious man and ask him what he wanted. ”

The hero said, "He wants wheat," and the king asked how much he needed, and he said, "I want the king to put one grain in the first square, two grains in the second square, four grains in the third square, and eight grains in the fourth square." Put them down one by one, multiplying by 2 each time. The sum of the 64 squares of wheat that filled the entire chessboard was the amount he wanted. ”

Zhang Yang's words paused and then said: "Ask how many wheat grains are needed to fill all the grids according to this condition." ”

After saying that, Li Chunfeng smiled, "What's so difficult about this?" ”

He was about to start the calculation, but when he reached the fifth grid, he stopped, and suddenly realized that this problem was not simple.

Zhang Yang and Li Yue continued to eat roast duck, which was a superimposed high-power operation.

"Do you know why foxes fall so often?"

Li Yue thought for a while, "How can a fox fall so often?" ”

Zhang Yang explained: "Because foxes are very cunning. ”

"Cunning?"

"Slippery feet."

Zhang Yang looked at Li Yue's feet emphatically.

Li Yue also looked at his feet, understood, and suddenly smiled.

Li Chunfeng looked up, and the princess and Zhang Yangzheng were smiling happily.

While calculating, it should not be wrong if it is calculated like this.

After a while, Li Chunfeng scratched his head in pain, counting to the eighth square, and the number became bigger and bigger......

It was getting late, the sunset was shining on this courtyard, the sun was shining on Li Chunfeng's body, and his eyes were a little dull.

The couple kicked the shuttlecock and had a lot of fun, Zhang Yang asked, "Has Li Chunfeng calculated it?" ”

Li Chunfeng gritted his teeth and looked at his own equation.

Mother, why is it so difficult, I am also a math master, if I am crushed by a half-sized child, I can't stand my self-esteem.

Another half an hour passed......

Li Yue put away the clothes and bedding that had been dried and said: "Li Chunfeng is long, it's not early, it's okay to count it tomorrow, don't be in such a hurry." ”

Li Chunfeng slowly stood up, "Since Her Royal Highness the princess said so, Poor Dao will go back first, Your Royal Highness Princess, please rest assured, Poor Dao will definitely be calculated." ”

With a somewhat weak footsteps, Li Chunfeng left the courtyard like a walking corpse.

Zhang Yang took a leisurely sip of tea.

After packing up the clothes and bedding, Li Yue said: "Is it difficult for the husband to come up with a question? ”

Zhang Yang said in a low voice: "Actually, there is a story to this question. ”

Hearing the word story, Li Yue had expectation in his eyes, "What a story, let's hear it." ”

"This story is about the story of a king who loves games and a very wise hero, and after that hero came up with this problem, the king calculated for a long, long time before he realized that even if he used up the wheat of the whole country, he would not be able to fill this chessboard."

Li Yue listened patiently.

"Since the promise given by the king must be fulfilled, the reward of the meritorious hero will naturally be given, but after the calculation, he will know where his land will come from so much food for him."

"Later, the king learned the origin of the hero, he came from a very poor place, the king played all day and did not know the suffering of the people, there were many people in the hometown of the hero, there were many people who could not eat, and many people died of hunger, and when the king asked him what he wanted, all he wanted was wheat."

"The king finally woke up to the fact that he did not want any glory and wealth, but only wanted the people of his hometown to be fed, and from then on the king would no longer have fun and take good care of government affairs."

Li Yue said in a low voice: "This is not just a math problem, this is also a story full of wisdom. ”

Zhang Yang said: "Actually, there is another ending to this story. ”

"What an ending."

"The king can continue to complete this problem, but let the hero count the wheat himself, grain by grain, which will be counted in tens or hundreds of years...... Later, the hero gave up and waved a butcher's knife to rebel. ”

Li Yue couldn't help but smile, "I still like the first ending." ”

Zhang Yang said: "Facts have proved that not to reason with the king is not only not beneficial, but also suffers from it. ”

The story of the wheat is a mathematical problem, constantly superimposed to the power of the power, and the calculation is a very large number at the end.

At night, Li Yue took a hot bath, her little face was flushed, she walked out of the room and said, "The clothes are not big enough." ”

Li Yue's little pajamas couldn't cover her waist.

It is the most important age for growth and development.

Seeing that Zhang Yang's trouser legs didn't cover his ankles, Li Yue sat on the edge of the table and supported his chin with one hand and said, "I'm going to make clothes again." ”

The light of the oil lamp shone on her little face.

Zhang Yang said: "Why don't you go and buy a few clothes." ”

Li Yue shook his head, "It's not good, I'm going to do it myself." ”

"Tomorrow we'll go see your fiefdom."

"Okay."

With that, she walked back to her room and closed the door.

It's rare that she can go back to her room to sleep, Zhang Yang let out a sigh of relief.

It was still warm tonight, and some cold air would still leak in through the window, Zhang Yang calculated the costs and benefits.

You can start a farm first, so that you can also produce and sell your own store, and the scale of the store can also be expanded.

You can also make a furniture industry and popularize the flush toilet first.

Well, that's great.

After washing up, Zhang Yang blew out the oil lamp and went to bed early.

Late at night, Taishi Bureau.

Two little eunuchs who were patrolling the palace at night passed by and saw Li Chunfeng holding a pen writing something on a very huge piece of cloth, and he kept muttering in his mouth.

Li Chunfeng's hair was scattered, and from time to time there were gusts of wind blowing here.

Seeing a strange scene in the middle of the night, the two little eunuchs sped up a little and left the Taishi Bureau.

After walking away, the two little eunuchs talked in a low voice.

"Yuan Daochang is already half crazy and half stupid, and this Li Chunfeng is also crazy."

"It's still chattering, it's scary."

"The monks are terrible."

"Let's hurry up and go back."

……

Taishi Bureau, Li Chunfeng's hand holding the pen was trembling, he was writing the equation and calculating, and his mouth unconsciously read it, 300,000 ...... Five thousand nine hundred ......

Pouring a mouthful of cold water into his mouth, Li Chunfeng grabbed his scalp painfully, "How many squares have you counted?" ”

“……”

"Twenty-nine, and ......"

Li Chunfeng's hands were trembling, and the pen fell to the ground, "There are still thirty-five grids." ”

Not to mention the calculation of each grid, but also the requirement of sum, how big is this number......

Is this what people can count?

Why is there such a painful subject in this world?

"Ahh Li Chunfeng let out a roar that almost collapsed in the middle of the night.

The most painful problem in the world is that you know how to calculate, but you just can't finish it.

Finally, Li Chunfeng swayed a few times, felt that the world was spinning, and finally couldn't stand up and fell to the ground, motionless......

The sky is white, and the quiet Chang'an City under the sun gradually comes to life.

I had no dreams all night and slept steadily.

Li Yue was still asleep in her room, and the two aunts got up early.

After washing up, I have to go out, and I haven't met with Cheng Chumo and them for a long time.

The bustle in Chang'an City is still there.

In the early morning, there are already a lot of pedestrians on the streets, and the festive atmosphere of the New Year has not yet passed.

When he came to the post house, Zhang Yang walked into the room, and Li Tai and Cheng Chumo were chatting without saying a word.

"Huh? Brother Chu Mo, were you struck by lightning while walking on the road? Zhang Yang looked at Cheng Chumo's hairstyle.

Where did the thunder come from early in the morning......

Li Tai yawned lazily.

"After the end of the court, my old man asked me to follow the officers and soldiers to investigate a case, and on weekdays, I would also help lead the soldiers and horses, saying that the investigation of the case could make a certain spirit wake up and use wisdom."

"It's a good thing, practice more wisdom."

"This case is also bizarre, the people of Dali Temple are also vague when they talk about it, and there is no end to the investigation, but they found a strange bamboo tube, saying that it was physical evidence picked up on the side of the road, and later when studying the physical evidence, I don't know which one did not have long eyes and threw the bamboo tube in the fire."

After the fireworks are set off, there may still be some residual gunpowder in the bamboo tube, which is also flammable and explosive.

"And then there was a loud bang, and the hair became like this."

Zhang Yang patted Cheng Chumo and said seriously: "Chumo,"

"Huh?"

"Don't pick up things on the side of the road."

Cheng Chumo was discouraged: "I know, fortunately, people are fine." ”

Looking at Cheng Chumo's hairstyle, Zhang Yang smiled unkindly, "Your hairstyle is still very avant-garde." ”

"If it weren't for the fact that he only beats up bad people and acts chivalrous now, I really want to chop up the person who is not long-eyed."

Zhang Yang arched his hand and said: "Don't mind, in fact, Brother Mo can be confident, after all, you have a good reputation in Chang'an." ”

Speaking of this, Cheng Chumo felt a little regretful, "It's a pity that that guy left Chang'an overnight with his family and softness." ”

Zhang Yang smiled dryly, speechless for a while.

offended Cheng Chumo, so he naturally didn't dare to stay in Chang'an City.

Cheng's family is fierce, and Cheng Biting Jin is not a loser, who dares to provoke him?

Changing his sitting position, Zhang Yang said, "By the way, what about profits?" ”

Li Tai said: "We all put the money in the store, you can pick it up yourself." ”

The guys at the inn served wine and meat.

Li Tai took a sip of wine and said, "The prince is really hateful. ”

Seeing that Cheng Chumo was about to pour wine, Zhang Yang took away his bowl and said, "Drinking in the morning is not good for your health." ”

Li Tai said another not-so-good news, and the cake business was still exposed.

The Wei Wangfu has the eyeliner of the current prince.

Li Tai is like a deflated ball, his eyes are blank at the moment.

Zhang Yang looked at him sympathetically and said, "Day and night, it's difficult to prevent thieves, be careful in the future." ”

"This prince actually complained to the queen mother, and said that this king is in the company of merchants all day long! Is this king that kind of person? The business matter has never come forward, why did he say that! ”

"It's really a villain to sue this kind of thing."

Hearing Zhang Yangneng say this, Li Tai was a little moved, "Sure enough, the hero sees the same thing, he is really a villain." ”

Li Tai is still a child with a lot of personality, but the prince can't come with his nature after all, in the eyes of many people, the prince should be like this, not like that.

The courtiers and civil servants all wanted the prince to live as they wanted.

But people can't live the same life as the assembly line, otherwise it will be a tragedy to lose their personality.

Li Tai poured wine while scolding Li Chengqian for half an hour, without breathing.

After taking another sip of wine and moistening his mouth, as if he was running out of words, Li Tai finally stopped.

"I'm a little tired, I'll scold another day."

Li Tai let out a sigh of relief.

Zhang Yang said with emotion: "His Royal Highness King Wei can scold people for half an hour, and I really admire it, even the shrews on the street are ashamed of themselves." ”

"What a shrew, this king is not a shrew!"

"That's right!" Li Tai cleared his throat and said, "Introduce someone to you." ”

After saying that, he clapped his hands, and a middle-aged man walked into the house, and he humbly bowed his head and bowed deeply.

Li Tai introduced: "He is Xu Jingzong, and he is also one of the eighteen scholars of the original father's Emperor Qin's palace. ”

Historically, Xu Jingzong was also a controversial figure.

This is also a smart person.
